(c1. as is) 2 Claims;

In education emphasis is -being placed on the teaching and instruction in various skilled tra-des. It is practically necessary to givethese teachings in industrial or tradeschools in view-'of ythe fact that in most trades the oldfashioned apprentice# ship system of learning vhas been abolished and" even Where young employees arefregarded as apprentices, they receive practically no training as skilled mechanics except such-as they may pick up by observation. One of the diiiicult skilled trades to teach and even tolearn by practical experience is that of Yplumbing which has all the ramications from smallcottages to large hotels, apartment houses and oilce buildings.

Moreover in learning vthe plumbing trade; it is necessary for the student to become acquainted with the particular municipal regulations and requirementsin the territory where he expects to Work.

A main object and feature of my invention is to facilitate education particularly as appliedto the building trades andhaving to do with installations such as plumbing, water service, electric and kindred equipment which enters into buildings quite separate and distinct fromY the l actual structuresV of the buildings which of course is usually done by skilled mechanics having spe'- cial lines of Work altogether'distinct from the art employed onl the actual erection or re-modelling ofbuildings. Another object of my inventionis to provide an educational appliance 0f miniature elements which is of decided use by a skilled artisan in learning how to install novel equipment and also to be of use in making layouts. for instance in rough plumbing usingthe miniature devices, therefore when the miniature is set up satisfactorily the actual fullY sized work can be done 'much more rapidly and without error necessitating changes.

, Therefore a further o 'bject of 'my invention and illustrated in connection with the Yinstallation Therefore a further and more detailed object of my invention is the construction of a framing simulating parts at least of a building made of a Wire mesh fabric preferably that having relatively and to be builtin as in a f large open square mesh type. In this I employ sheets of fabric designated as vpanels connected at corners and angles by slotted brackets", angles, Ts, etc. of this type. Thus with these wire panels and the specially designed brackets, a structure may be readily built .up and dismantled giving a suicient simulation of walls, partitions, floors,

ceilings, etc. of a building. Y Y

My invention also Acomprehends the miniature plumbing elements which are made of the same shape as those used vin plumbing including straight pipe, elbows of various angles, Ts, traps, etc. In order to facilitate the assembly of the different elements, they are preferably provided with dowels or pin and socket connections. Then with the miniature plumbing elements, the rough plumbing `may be set up i-n proper relationship with the wire andJnesh panels, the wires of the mesh maybe cut and bent to hold theV fittings in -place and thus the'whole assembly is built up vas it Wouldbe in actual construction.. In'view of the fact that, the wiremeshvpanels are quite inexpensive, ,when toomany cuts have been made in the individual wires to hold the elements, a panel maybe discarded but the miniature ttings may be yused over and over again.

My invention is `illustrated in connection v.with c the accompanying drawings, in which:

Referring rst toy Fig.-1, a sectionof a building isgindicatedn bythe numeral II.A This is. shown Sections ofA @The manner made of the panels above mentioned forrough F 2 Y These various panels areshown as held in place byvarious shapes of channel brackets. Each of the panels is indicated as `made of wire mesh and preferably of a type having a square or rectangular mesh. y

For instance, some of the types of corner or I angle brackets are substantially as follows:

A single corner channel bracket 30 Ais illustrated as having double channels 3I and 32 meeting atthe cornerV 33 and having a connecting triangular web 34 atthe base or bottom of the channels. verticalfedge 35 and also open at a top edger36. The brackets when lmade up are quite `substantial The bracket of Fig. 4 designated as-theY double ,Y

These channels are thus .open ata corner channel bracket 40 may be considered as f made up of two brackets similarl to Fig. 5 having the upper angle channel 4II and the lower angle.

head 52 there are also the' openings in each channel facing upwardly-M It is of course obvious that the type of channel brackets of Figs. 3 or 5 may be used in anrinverted, that is;,an upside down position'when so desired. y n 1 Referring tov Fig. 4, it will therefore be seen thatther floorV panels I2 andV I3 and the -wall panel I4 are held in place by the Tbracket 50 at the front and rear, there being two of these Vtypes offbrackets. The wall panel I3" and theA 'ceiling or iloorlpanel, I'I are heldin placeby the double channel bracket 40 ofVv Fig.`4. This may be fitted atthe four cornersrof the ceiling Vor floor panel I1, three ofthese onlyvbeing illustrated in order vto simplify the' illustrationV and expose the interior ofthe structure. `The corner formed bythe oor panel |2, the side wall panel I5 and the back wall panel I0 isrillustrated as connected in the single bracket 30. This-bracket and that immediately above illustrate the'horifloor of a house or underneath a cellar :floor where the drain pipe is buried in the ground. This pipe is made up of straight pipe sections 62, a type of curved elbow T 63 is also illustrated, this latter having the head section 64 and a curved stem section 65. In constructing these miniatures I prefer to make them simulating as close as possible without undue cost to manufacture, the actual plumbing fixtures, therefore at each end ofthe T there is shown-a bell and spigot type of joint 66 but of course as no water is to run through these miniature pipes they may be made solid and the bell and spigot may be considered as a socket and dowel pin connection.

strands A'ILI of the'wall panel I4. A second T 80 is illustrated as having the stem 8| extending through 'an' openingy 82 in the vertical wall I4. If theopen space of the mesh fabric is of insufficient size, one or more strands may be cut to afford the proper opening and also to locate such opening in theproper position. The strands -zontal fabric resting on a triangular web.Y It

will be seen that merely by employing'brackets Y such as shown in Figs. '34 `and5r or, a further similarV type that aflarge yvariety ofshape's and sizes 'of panels may be built up`and1 held sufliciently rigid for the purpose 'of' developingy a framing with approximately the characteristics Vof a building constructionin ,which thepliimbing is to be insta1led. In viewfof the, fact that each of the panels is'rmade up of a wire mesh fabric, the individual wires may be designated as strands. The .particular structure of Vthese,

wire fabrics lis no part of my invention as there are satisfactory types now on-the market which secure the vT in place.

cut informing this opening may be utilized Ato A vent pipe. construction '85 is shown by'l a series ofkventv pipe sections 86 leading upwardly .from the drain pipe. and from the T 80. This extends above the top ofthe Wall panel I4 above the ceiling or floor panel I'I and may have an- In( Fig. 1 I alsoL illustrate in .a conventional manner Aa water supply installation-90. This is indicatedas having a main supply pipe 9| presumed toilead from the water main, this passing underneath the panel I3 and upwardly through an opening 92. A .vertical section 93 is placed contiguous Vto the outside ofthe wall I4, lan elbow 94 connectedto the vertical pipe 93 has a horizontal pipe runv95 connected thereto. A T

This water pipe and its various necessary 4fittings is likewiseattached y.to the fabric panels by cutting 'strands and bending these to engage the pipe..

Fig. 6 illustrates a series of plumbing ttings `connectedfwith floor and wall panels together with various nished plumbing elements shown may be purchased in large sheets atquite modl erate pricesiand cutinto the sizes.. v f .n of using the fabricated structure plumbing is indicated by therough plumbing indesired .shapes y'and be considered' either as `underneath the ground in dotted lines.- For sakevof completenessof the illustration Vof Fig. 6, a fabric floor panel is indicated by-the numeral |00 Vand a Vvertical wall panel by 'the .numeral |0|,.each of these being of the rectangularvwireme'sh. Underneath vthe oor panel is a lineof Q'drainage pipe |05, this being`built up of a series of straightpipe sections V|0I5 and a series of Ts |01. The end T I08 is shown as having a removable clean-out plug |09. 1 'Ihe iloorandl wall panels both have strands out Aand bent to hold the drain pipe and the various Ts in position. v i j Extending upwardly from the various Tsthere are a, series of `standpipes |20, each of which has anpelbow 'I2I attached thereto. y From certain of these elbows are connected traps such as |22, this connected traps are indicated as connected to a Wash basin |363, a bathtub ISI. tray indicated at |32 necessitates a connecting pipe |33 to the trap. As the water closets |35 usually have a trap built therein, an elbow E35 makes a connection to a vertical T which in its turn leads to the drain pipe system.

The vent connection or systems are shown as having a main riser |4| from the water closet pipe system and secondary vent risers m2 leading upwardly from the Ts connecting to the various ittings such as the Wash basin |39, the bath |3l, and the shower bath tray |32. A horizontal Vent pipe run U53 connects into the vertical secondary vent pipes as for instance by Ts idd, an elbow |135 and these in turn connect to the main Vent standpipes mi) by a T |576. All oi these sides and connectingT elements are made in miniature having a suitable bell and spigot connection or a socket and dowel attachment. Where special fittings are used with an adjustable collar, these may also be installed in the miniature plumbing system. The wire fabric of the panels affords a structure for holding the assembly in place by slitting strands and bending these to engage various elements of the construction. It will therefore be seen that after the assembly has been completed, it is held in place in proper relationship to the various panelsbut may be readily disconnected for making changes or rearrangement to secure a better set-upv of the whole plumbing scheme. It is obvious that in these miniature structures suchvas in Fig. 6 the water supply of bothhot and cold water may be likewise built in place similar to the water supply A connections 9|) of Fig. 1 and held in proper position on the panels and in relation to the various fixtures. Where desired miniatures of the fixtures may also be utilized such as the wash basin |30, the bath |3|, the shower tray |32 and the water closet |35, however for sake of clarity of illustration, these have been shown dotted instead of in full lines.

My invention as above mentioned comprehends A shower bath not only the use of miniature elements of construction used in plumbing such as the sewerage or drainage system, the vent system, but also the water supply. Further, my invention includes rthe use of miniature devices and fittings for other common services in building construction Y such as the gas pipe connections with their various elements, the electrical installation including conduits, switch-boxes, wall box connections and other similar structures of a type coming under the general head of electrical Wiring for houses or building constructions.

Various changes may be made in the details of the construction without departing from the spirit or scope of the invention as defined by the appended claims.

I claim:

1. A device o the class described comprising a plurality of panels, means for detachably fasten# ing the panels together Ato represent the oor, Walls, and ceiling of a building, a plurality of detachably connected miniature service fittings adapted to be applied tothe structure to represent service fittings of a building, the panels being formed of crossed Wire strands of sufficiently wide mesh that when a strand is cut adjacent its crossing another strand the freed portion of the strand which is freed by the cutting is suicient in length to partially encircle a service fitting to hold the fitting against the panel `from which the strand is cut.

2. In a device of the class described a plurality of panels adapted to be assembled to form a floor, Walls, and ceiling representative of the iioor, walls, and ceiling of a building, and brackets for holding the panels in assembled relationship, each bracket comprising at least two panels arranged at an angle to each other and designed to receive corner portions of wall-forming panels, each bracket having corner webs connecting the panels adapted to support floor or ceiling-forming panels.
